To all whom t may concern:

Be it known that I, JONATHAN SMITH,

born in the town of Duxbury7 Massachu setts, and now resident inNeponset village, in the county of Norfolk and State of Massachusetts,have invented a new and Improved Method of Holding Vessels by the Keelin Dry, Sectional, or Railway Docks; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon.

B is a keel block which rests on and is confined to the bearer A.

C is a pawl which Slides in the Straps or hasps D and E, by which strapsit is conlined to the keel block B and the bearer A.

F F is a rope or chain attached to the pawl C and led through a block tothe Side of the dock`by which the pawl C can be hauledv down.

Cr G is a rope attached to the pawl C and led through a block to thesides of the dock by which the pawl may be raised. It is intended thatthese pawls Should be used in pairs.

When hauling a vessel on the dock the pawl on the opposite side to wherethe vessel is should be raised and the vessel hauled against it and thenthe Opposite pawl raised which will confine the vessel on the middle ofthe keel blocks between the two pawls.
